4 Claims.

This invention relates to separable fasteners employing stringers coupled by a slider movable.

longitudinally of the linked edges of stringers.

More particularly, the invention relates to means for reinforcing the bottom stop and the stringer tapes adjacent the bottom stop in adapting the fasteners to predetermined uses where the stringers are subjected to lateral stress or strains, adjacent the bottom' stop thereof. The novel features of the invention will be best understood from the following description when taken together with the accompanying drawing, in which I Fig. 2 is a section substantially on the line 2-2- of Fig. 1, illustrating the slider in side elevation.

Fig. 3 is a partial section on the line 3-3 of Fig. 1.

Fig. 4 is a view similar to Fig. 1 showing another adaptation of the invention.

Fig. 5 is a section on the line 5-5 of Fig. 4.

Fig. 6 is a view similar to Fig. 4 showing another modiflcation; and,

Fig. 7 is a section on the line 1-1 of Fig. 6.

In certain uses of separable fasteners of the kind under consideration, the fasteners are subjected to lateral stress or strain, tending to separate the stringers particularly adjacent what is referred to as end or bottom stop. Such experiences are common in various kinds of apparel, and particularly in the application of fasteners of this kind to the trouser fly. It is the purpose of my invention to provide a very simple and economical means for reinforcing the end stop as well as the stringer tapes adjacent the end stop to take up the stress or strain to which the stringers are subjected.

In Figs. 1 to 3 inclusive, I have shown one adaptation of the invention; and in these figures, l0 and H represent the lower portions of two stringer tapes to the beaded edges Ilia, Ila, of which are attached the links or scoops l2, l3, which are coupled and uncoupled by a conventional slider ll, movable along the stringers. At l5gis shown an end stop plate having two pairs of prongs l6 which are adapted to pass through the tapes l0 and ii adjacent the beaded portions Ilia, I la, and crimped over as seen in Fig. 1 in securely coupling the tapes together. This construction as described is more or less conventional.

In practice I provide a reinforcing tapelfi, the central portion ll of which is arranged across the tapes l0 and-i i, adjacent but in spaced relation to the end stop IS. The end portions l8 and'l9 of the reinforcing tape are folded inwardly and the latter reinforcing the end stop l5 against Y., a cordownwardly on the fold lines 20 to cross at a point in alinement with the end stop l5 as seen at2l so that the prongs also pass through the overlapped and crossed portions of the tape as is clearly indicated. 'The terminal ends- I and i9a of the folded end. portions l8 and I! extend beyond the crossed overlapped portions 2| as will be clearly seen in Fig. 1 of the drawing.

With the construction shown in Figs. 1 to 3 in- 'clusive the reinforcing tape becomes a permanent part of the complete stringer; and it is preferred that the various end portions of the tape which extend onto the stringer tapes be unattached.

However, in some uses, these ends may be teinporarily attached simply to hold the parts in position, or as taught in the other figures of the drawing, an adhesive may be employed simply toretain the parts in position. However, I havefound in actual practice that no independent securing means is required. It will be understood that when the fastener is attached to its support by lines of stitching 22 extending longitudinally of the stringer tapes, these stitchings will also pass through the parts l1, l8 and I l of the tapes and may also extend through the terminal ends l8a, l9a. It will thus be seen that when the fastener is attached to the garment or other support, the stringers will be reinforced againstlateral separating stresses. or strains by the transverse reinforced tape portion ii. The

stringers will be furthenieinforc'ed by the. ang-.

ularly disposed and crossed end portions l8, l9,

opening stresses or strains. In fact, with a struc ture of the type and kind illustrated, the slider l4 will be checked in its downward movement by the crossed tapes l8, l9, as indicated at 23 in Fig.2 of the drawing, rather than by the stop plate I! itself, thus providing a good cushioned checking of downward movement of the slider.

In Figs. 4 and 5 of the drawing, I have shown another adaptation of the invention wherein stringer tapes 24, 25, are employed, these tapes having interengaging coupling links 26 and 21.

In this construction, instead of initially permanently coupling the tapes 24, 25, together by an end stop plate similar to the plate IS, the stringer tapes are left uncoupled so as to facilitate independent stitching of the tapes to separate supports, after which a plate similar to the plate I5 is secured in position. With this construction a reinforcing tape 28 substantially similar to the tape 16 is employed, the tape having a central transverse portion 29 and inwardly folded and crossed end portions I30, 3!. 1 The end portions 30, I

3| are cemented together where they cross each other as indicated at 32 whereas the terminal end 30a of the end portion 30 is cemented to the tape 25 as seen at 33, and the parts 29 and 31 are cemented to the tape 25 as indicated byfthe dotted lines 34.

. It will thus be seen that thereinforcing tape unit 28 becomes a unit part of the stringer tape II, but is unattached to the tape 24. With this construction, the stringer tapes may be separated by the usual slider "and independently at- ,tached to different supports. If necessary, a

special line of stitching may be provided in 5 curing the reinforced tape portions to the 'support and the stringer tape '24. However, in many uses. the tape 25 will first be secured to one support and then by a single line of stitching, the tape 24 will be attached to its support and simultaneously coupled with the tape 25 by. passing the stitchings through the reinforced a further adaptation of the invention which con-- sists-in using what might be termed a half section ofthe tapes as illustrated in Figs. 1 to 5, in-

elusive: or-in other words, by eliminating one of the angularends of the tape. In this construc: tion the stringer tapes; are identified as a, Ila, with the links "a, 21a=on one edge of the tape. At 3! is shown a reinforced tape unit comprising the transverse part. It, similar toth'e part It,

and the'angularly extending end 31, similar to the end ll. I

The it and 31 are cemented together where foldably coupledQnd to the tape 2! as indicated bythe dotted lines II and 3! ,in Fig, 6, whereasthe ends of theparts 3O, 31 are'free and unattached tofthe tape 244, as in the shown in Figs. 4 and 5. This fastener will be attached in the same manner as-the fastener illustrated in Figs, 4 and 5, and further descriptioninthisregardisunnecessary. Itwillbe well to mention, however, that with the structure shown in Figs. 6 and 7, the end stop plate, similar to the plate II, when attached, is passed through the part 31a of the end portion 81 where it overlaps the adjacent beaded edges of the tape 24, 25, just beyond the end links of said tape.
